PROTON controller regulator for a loading furnace boiler - PID algorithm

This controller continuously and automatically controls the blower and maintains the temperature set on the boiler at a constant level. This solution prevents sudden temperature spikes in the boiler. Using this controller improves user ergonomics: there is no need to adjust the controller settings when changing the fuel.

The PROTON PID controller also has a number of functions with which the PROTON controller was equipped.

Smooth blower speed control - NEW ALGORITHM
The PROTON PID controller allows setting the maximum and minimum blower speeds, enabling precise adjustment of the power at which the blower will operate.
Gradual activation of the blower from minimum to maximum speeds extends the motor's lifespan and prevents sudden ignition of gases accumulated in the boiler (so-called popping). Competitor controllers have only one parameter responsible for blower power – in the PROTON PID controller, you can set both minimum and maximum speeds.

Fuel control
This function reduces the blower speed to a minimum when the controller detects a temperature drop despite the blower being on. Reducing the blower speed does not cause excessive cooling of the central heating boiler. This function activates after 30 minutes if the set temperature has been reached, or after 2 hours if the set temperature has not been reached (ignition mode – 2 hours).

Anti-freeze function
Below 5°C, the controller turns on the circulation pump, which delays freezing of some parts of the central heating installation (the most vulnerable ones).

Anti-stall function
After the heating season, every 14 days the circulation pump is turned on for 1 minute – this prevents the pump from seizing during the summer – the function works when the controller is on.

Automatic saving of settings
The controller automatically saves settings during power loss and resumes the previously performed operation after power is restored.

Return to factory settings
The controller can return to factory settings. This function is useful when the controller is misadjusted by inexperienced operators.

Automatic emergency thermostat
An external thermostat (emergency thermostat) serves as protection against overheating, which may result from controller failure or improper operation. It is a special element that cuts off power to the blower at a boiler temperature of 90°C.

User-programmable parameters
Blow time, pause time between blows, maximum and minimum blower speeds, circulation pump activation temperature, controller shutdown temperature.

Installer-programmable parameters
Besides the configuration mode available to every user, the PROTON PID controller has a special mode that allows setting service parameters (additional service manual).
The service mode allows programming:
blower characteristics – thanks to this parameter, our controller can work with any blower available on the market (up to a specified max. power)
blower power during blowing – you decide the power at which the blower operates during blowing
blower speed reduction range – how many degrees before the set temperature the blower speed should decrease
minimum boiler temperature

REMOTE CONTROL OPTION
A remote control panel or room thermostat can be connected to the PROTON PID controller. Connecting a remote panel allows the controller to operate in two modes: room and boiler. Connecting a standard room thermostat allows maintaining the set temperature in the room. Thanks to remote control, we can maintain a constant room temperature, which saves fuel by up to 30%.
